Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a femoral condyle prosthesis and an artificial knee joint. The femoral condyle prosthesis comprises a femoral condyle basis body and a cam; the cam is arranged in an intercondylar box of the femoral condyle basis body, and is rotationally connected with the intercondylar box. The artificial knee joint comprises the femoral condyle prosthesis. The femoral condyle prosthesis and the artificial knee joint aim at solving the technical problem that in the prior art, the contact part between a standing column and the cam is seriously worn.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a femoral condyle prosthesis and an artificial knee joint. Background technique [0002] The artificial knee prosthesis is implanted into the human body after knee replacement, and its function is to restore the normal physiological functions of the human body. In knee replacement surgery, if the patient's lesions are severe and the posterior cruciate ligament cannot be preserved, it needs to be resected during the operation. For patients who have had the posterior cruciate ligament resected, only a posterior-stabilized prosthesis (ie, PS-type prosthesis) can be used for surgery. [0003] For the posterior stabilized knee prosthesis, since the posterior cruciate ligament is resected during the operation, a column-cam mechanism (ie, POST-CAM mechanism) is set in the artificial knee joint to simulate and replace the function of the posterior cruciate ligament. The posteri...
